decommission-validated-system

decommission-validated-system is a skill for Claude Code from pjt222/agent-almanac. It costs 83 tokens per session (2,329 once invoked), scanned A, original, MIT.

A controlled process for retiring a regulated computer system while keeping its records usable and compliant. It covers retention, data migration checks, archiving, access removal, and stakeholder communication.

In plain words
What is it for?
Use it to plan system retirement, assess retention requirements, validate data migration, archive documents, revoke access, and notify affected people.
Why use it?
It reduces the risk of losing records, corrupting migrated data, or breaking regulatory retention rules when a validated system is replaced or shut down.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

decommission-validated-system scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Decommission Validated System

Plan and execute the controlled retirement of a validated computerized system while preserving data integrity and meeting regulatory retention requirements.

When to Use

  • A validated system is being replaced by a new system
  • A system is reaching end-of-life with no replacement (business process eliminated)
  • Vendor discontinues support for a validated product
  • Consolidation of multiple systems into a single platform
  • Regulatory or business changes render a system obsolete

Inputs

  • Required: System to be decommissioned (name, version, validation status)
  • Required: Data retention requirements by regulation (21 CFR Part 11, GLP, GCP)
  • Required: Replacement system (if applicable) and migration scope
  • Optional: Current validation documentation package
  • Optional: Data volume and format inventory
  • Optional: Business owner and stakeholder list

Procedure

Step 1: Assess Data Retention Requirements

Determine how long data must be retained and in what form:

# Data Retention Assessment
## Document ID: DRA-[SYS]-[YYYY]-[NNN]

### Regulatory Retention Requirements
| Regulation | Data Type | Retention Period | Format Requirements |
|-----------|-----------|-----------------|-------------------|
| 21 CFR 211 (GMP) | Batch records, test results | 1 year past product expiry or 3 years after distribution | Readable, retrievable |
| 21 CFR 58 (GLP) | Study data and records | Duration of study + retention agreement | Original or certified copy |
| ICH E6 (GCP) | Clinical trial records | 2 years after last marketing approval or formal discontinuation | Accessible for inspection |
| 21 CFR Part 11 | Electronic records | Per predicate rule | Original format or validated migration |
| EU Annex 11 | Computerized system records | Per applicable GxP | Readable and available |
| Tax/financial | Financial records | 7-10 years (jurisdiction-dependent) | Readable |

### System Data Inventory
| Data Category | Volume | Format | Retention Required Until | Disposition |
|---------------|--------|--------|------------------------|-------------|
| [e.g., Batch records] | [e.g., 50,000 records] | [e.g., Database + PDF reports] | [Date] | Migrate / Archive / Destroy |
| [e.g., Audit trail] | [e.g., 2M entries] | [e.g., Database] | [Same as parent records] | Archive |
| [e.g., User data] | [e.g., 200 profiles] | [e.g., LDAP/Database] | [Employment + 2 years] | Anonymise and archive |

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
